Heaters

What is the protective design principle behind Armored Heaters?
1. Synergistic Protection of Metal Casing and Alloy Heating Wire

A high-strength metal casing encases the alloy heating wire, creating a robust mechanical barrier to protect against shock, vibration, and external impact.

The metal casing also effectively shields electromagnetic interference, enhancing the heater's electrical safety.
2. High-Temperature Corrosion Resistance of Insulation Material

High-temperature and chemical-resistant insulation material is used internally to isolate the heating wire from the external environment, preventing short circuits and leakage.

The insulation layer also suppresses heat loss in unwanted directions, improving thermal efficiency.
3. Flexible External Protective Tubing Design

The small-diameter, long-length external protective tubing can be bent into various shapes to accommodate complex piping layouts.

This tubing not only provides secondary protection but also reduces stress concentration during installation, extending its service life.
4. Multi-Mode Heat Transfer Mechanism

Heat is transferred to the heated object through radiation, convection, and conduction, achieving uniform and rapid heating.

This combined heat transfer method improves overall thermal efficiency and meets demanding industrial heating requirements. What are the key maintenance points for armored heaters?
1. Regularly check the housing integrity

Inspect the metal housing for cracks, deformation, or signs of corrosion, and replace damaged parts promptly.
Ensure the bolts fastening the housing to the terminal blocks are secure to prevent loosening and electrical failure.
2. Inspect the insulation integrity

Use an insulation resistance meter to measure the insulation resistance to ensure it is not damp or deteriorating.
If cracks or peeling are found, replace it immediately to prevent short circuits and leakage.
3. Clean surface deposits

When operating in an environment with high levels of dust, oil, or chemicals, clean the heater surface regularly to prevent increased thermal resistance.
Use a soft, dry cloth or specialized cleaning agent; avoid using highly corrosive solvents.
4. Thermal performance verification

Monitor the actual temperature distribution of the heater using a temperature sensor or thermal imager to confirm uniform heat transfer.
If localized overheating or temperature deviations occur, check the internal heating wires for damage or poor contact.
